We show that optomechanical systems can test the Schrödinger-Newton
equation of gravitational quantum mechanics due to Yang et al. Phys. Rev. Lett. 110, 170401 (2013). This equation is
motivated by semiclassical gravity, a widely used theory of interacting
gravitational and quantum fields. From the many-body Schrödinger-Newton
equation follows an approximate equation for the center-of-mass dynamics of
macroscopic objects. This predicts a distinctive double-peaked signature in the
